Volcanoes are fascinating, devastating, and fundamental to Earth systems. Volcanic eruptions can transform ecosystems, landscapes, and even the atmosphere, and at their most extreme, the effects of volcanism can be global and long-lasting. In this overstuffed episode, we discuss the many forms and features of volcanic activity, and we take a look at the complex and dramatic interaction between volcanoes and life on Earth.

In the news: ankylosaur brains, an Australian rainforest, donkey hybrids, and the Tonga volcanic eruption.
